There is need to breed for high-yielding maize genotypes to meet up with the needs of the fast-increasing population in Nigeria and West and Central Africa (WCA) in general. Seven maize genotypes were collected from the Institute of Agricultural Research and Training (IAR&T), Ibadan, Nigeria and crossed in Line x tester mating design at the Teaching and Research Farm of Federal University of Agriculture, Abeokuta, Nigeria (FUNAAB) in 2014. The parental inbred lines used in the crosses and hybrids generated were evaluated at FUNAAB and the Oyan Project site of Ogun Oshun River Basin Development Authority, Nigeria, in 2014. Data collected on grain yield and other yield-related agronomic traits were subjected to analysis of variance (ANOVA) which revealed significant (p < 0.05) entry effects with respect to all the traits except days to anthesis and number of kernel rows per ear. Mean separation was performed for all the characters using Duncan's multiple range test (p ≤ 0.05). Analysis of combining ability effects revealed significant (p ≤ 0.05) general and specific combining ability effects for all the characters. Estimates of dominance variance (σ2SCA) were larger (-0.002 to 166565.220) than additive variance estimates (σ2GCA) (-0.10 to 4638.39) for all traits that were considered. 1000-kernel weight was identified as most reliable selection index for yield improvement in maize breeding. Genotypes FAM-98-129 and FOM 128 were found as the best maternal line and best pollen parent, respectively. Hence, they are suggested for use in future breeding programs.

East related those biological principles to the more practical plant improvement studies to achieve his goals (Hayes, 1956). The progeny test was defined by Allard (1960) as ‘a test of the value of a genotype based on the performance of its offspring produced in some definite system of mating.’ It was used as early as 1850 by Vilmorin in France, and it proved to be a highly effective procedure for the improvement of sugar content of sugar beets (Beta vulgaris). This method of line selection with progeny testing was known as the ‘Vilmorin method’ or ‘Vilmorin isolation principle’ and was introduced in several plant breeding programs in the latter part of the 19th century. The progeny test in maize was first used in 1896 by Hopkins, starting the well-known program for half-sib recurrent selection of maize oil and protein content (e.g., the ear-to-row half-sib selection procedure).
